Topotactic-hydrogen forms chains in O nickelate superconductors
Liang Si, Paul Worm, Dachuan Chen +1
Despite enormous experimental and theoretical efforts, obtaining generally accepted conclusions regarding the intrinsic magnetic and electronic properties of superconducting nickel…
Merging numerical renormalization group and intermediate representation to compactify two- and three-point correlators
Sebastian Huber, Markus Wallerberger, Paul Worm +1
The vanguard of many-body theory is nowadays dealing with the full frequency dynamics of n-point Green's functions for n higher than two. Numerically, these objects easily become a…
Optimizing superconductivity: from cuprates via nickelates to palladates
Motoharu Kitatani, Liang Si, Paul Worm +3
Motivated by cuprate and nickelate superconductors, we perform a comprehensive study of the superconducting instability in the single-band Hubbard model. We calculate the spectrum…
Signatures of topotactic hydrogen in nickelate superconductors
Liang Si, Paul Worm, Karsten Held
Superconductivity has entered the nickel age marked by enormous experimental and theoretical efforts. Notwithstanding, synthesizing nickelate superconductors remains extremely chal…
Phase diagram of nickelate superconductors calculated by dynamical vertex approximation
Karsten Held, Liang Si, Paul Worm +5
We review the electronic structure of nickelate superconductors with and without effects of electronic correlations. As a minimal model we identify the one-band Hubbard model for t…
